Sql Server Updating column by generating random number

I try to update my column with random number in sql server 2008 R2.

For example myTable is like below :

id  password
1   NULL
2   NULL
3   NULL
4   NULL
4   NULL
5   NULL
5   NULL
5   NULL

When I update password by generating 5 digit random number, table be like

UPDATE myTable
SET password =   CONVERT(numeric(5,0),RAND(convert(varbinary,newid()))*89999)+10000

id  password
1   87781
2   15395
3   62154
4   74194
4   49599
5   54090
5   47287
5   63193

And, My problem is generating password for each id. Could help me about query which is giving that result :

id  password
1   87781
2   15395
3   62154
4   74194
4   74194
5   54090
5   54090
